That sounds like a wonderful time at retreat, BookSaver. About choosing neckline designs for making tops - you might want to consider jewelry too, in those decisions. See if you can design the neckline to complement a necklace you might add to its look. Either just high and simple enough to be a pretty background, or low enough to allow necklace to fall above, or directly along the edge. Along the edge looks better than I used to think it did.
I was very pleased to find recently that a sort of complicated blue pendant necklace I own falls directly on-line of the "V" neckline of a simple navy solid top I bought. When I wore it to church Sunday it looked as though they had been purchased to go together and it made the ordinary top look quite "rich", lol. That was a revelation to me.
Just as I posted in H and F, I will need some normalcy (and space from so much social stuff) before I can get back to projects. I want to make some bookmarks but you have to have a very still and calm house to work with tiny dried blossoms. I'd like to get to some sewing, but I need those chunks of time that are hard to come by.
